STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphates from the
lead plates of the battery restoring the battery capacity.
STEP 2 SOFT START
Tests if the battery can accept charge. This step prevents charging a defective battery.
STEP 3 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 4 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 5 ANALYSE
Tests if the battery can hold charge. Batteries that cannot hold charge may need to be
replaced.
STEP 6 RECOND
Select the Ca/Ca program to add the Recond step to the charging program. During the
Recond step voltage increases to create controlled gassing in the battery. Gassing mixes
the battery acid and gives back energy to the battery.
STEP 7 FLOAT
This step maintains the battery voltage by providing a constant voltage charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage
and gives a pulse when necessary to keep the battery fully charged.
WAKE UP
Safely bypasses the discharge protection if active on the battery.
STEP 1 ACCEPT
Tests if the battery can accept charge. This step prevents that charging proceeds with a
defect battery.
STEP 2 BULK
Charging with maximum current until approximately 90% battery capacity.
STEP 3 ABSORPTION
Charging with declining current to maximize up to 95% battery capacity.
STEP 4 ANALYSE
Tests if the battery can hold charge. Batteries that can not hold charge may need to be
replaced.
STEP 5 COMPLETION
Final charge with increased voltage.
STEP 6 MAXIMIZATION
Final charge with maximum voltage up to 100% battery capacity.
STEP 7 FLOAT
Maintaining the battery voltage at maximum level by providing a constant voltage
charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage
and gives a pulse when necessary to keep the battery fully charged.
